20917840 divided by 250 
The aim is to understand the frequency of 250 in 20917840.

Moving on to step 1:
250 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 250

Step 2:
250 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 250

Step 3:
250 can be fit into 209 0 times, resulting in a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 209 to get 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 250

Going ahead to step 4:
250 can be fit into 2091 8 times, resulting in a remainder of 91.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 2000 away from 2091, we end up with 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 250

On to step 5:
When dividing 917 by 250, we get 3 with a remainder of 167.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 750 from 917, we get 167.
Bring next digit (8) of the dividend behind the 167 and repeat the process: 1678 / 250

Moving on to step 6:
When dividing 1678 by 250, we get 6 with a remainder of 178.
Write down 6 as next digit of the result. 
Result so far: 836.0
If we subtract 1500 from 1678, we get 178.
Append the next digit (4) from the dividend to 178 and continue with: 1784 / 250

Advancing to step 7:
If we divide 1784 by 250, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 8367.0
Deduct 1750 from 1784 and we're left with 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 250

On to step 8:
250 goes into 340 1 times with a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 83671.0
The remainder is 90 after subtracting 250 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
250 goes into 900 3 times with a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 83671.3
If we take 750 away from 900, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 250 fits into 1500 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 83671.36
The remainder is 0 after subtracting 1500 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
250 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 83671.36
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 250 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83671.36
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 83671.36 with a remainder of 0.0.
